GCP Authentication Filter: Update the API proto for audience.

[tyxia]

map is not needed for the audience url (and no lookup is performed anyway because the key is currently a fixed string..). The audience URL is provided to the filer extension through cluster's typed_filter_metadata . And the cluster selection is based on the information in each route : context_.clusterManager().getThreadLocalCluster(route->routeEntry()->clusterName());.

So the correctness of type_filter_metadata is already guaranteed by the lookup at cluster level (i.e. getThreadLocalCluster()) based on destination cluster information in the route and no lookup of map struct is needed here.
